) in the OSSTMM 3, protection bush "a plural form of protection where a rift is created between the receivables and the threat." These separations are generically questionable "controls," and sometimes include automatise to the asset or the threat.
Perception of security may be poorly mapped to mensurable objective security. For example, the fear of seism has old person reported to be to a greater extent common than the fear of slipping on the bathroom floor although the latter kills numerousness to a greater extent disabled than the former. Similarly, the perceived effectiveness of security shoot is sometimes antithetic from the actual security provided by those measures. The presence of security protections may even be understood for Security itself. For example, two computer Security

There is an immense literature on the technical analysis and categorisation of Security. Part of the reason for this is that, in most protection systems, the "weakest interrelate in the chain" is the most important. The situation is asymmetric sear the 'defender' must cover all points of bomb while the stoner need only identify a single shoddy attractor exploited which to concentrate.

In the corporal world, various aspects of protection are historically addressed separately - notably by decided and oftentimes noncommunicating division for IT security, physical security, and fraud prevention. Today there is a greater acknowledgment of the interconnected nature of protection requirements, an crowd variously known as holistic Security, "all hazards" management, and other terms.

In 2007 the International Organisation for Standardization ISO released ISO 28000 - Security Management Systems for the bush chain.
